Understanding How NEAR Scales with Nightshade

NEAR protocol enters the web3 space with a host of innovations both at the level of its underlying technology, and its overall mission to put usability first. Central to both of these is its game-changing scalability solution known as Nightshade, which implements a unique sharding protocol that will ultimately lead to what it calls a ‘’fully-sharded’ network. This blog will provide a recap on the need for scalability in blockchains, some of the existing solutions on the market, and how NEAR disrupts and innovates within this space. It will then go on to underscore the importance of NEAR smart-contract audits as a means of bolstering the underlying security of the NEAR ecosystem, and equipping NEAR projects with the confidence they need to succeed. — Scalability problem recap - First, let’s recap the blockchain scalability problem, and why it is so important. As its name suggests, the scalability problem refers to the challenge blockchains face in being able to continue to function as they scale to serve a wide user base. This is difficult because of blockchain’s need to also be decentralized and secure– in what Vitalik Buterin famously coined as the blockchain trilemma. Within a network with a small user base this isn’t a problem, as the network has the throughput to process transactions faster than they are occurring. However, as blockchain technology grew in popularity, the networks struggled to proces...

How NEAR is Driving Innovation in Game-Fi

Game-fi is increasingly touted as a key on-ramp for initiating new users into the web3 ecosystem. With such an avid gaming community hungry for new ways to play and interact, game-fi offers an open door into not only new games, but also new forms of gaming. NEAR is leading the way in this sector by providing a technology that is uniquely suited to providing game-fi developers the platform they need to create. This article will run through why game-fi is set to be a pillar of the web3 ecosystem, how NEAR’s technology is geared to support it, and the importance of NEAR smart-contract audits in securing game-fi for the future. Gaming in the Web3 Ecosystem Gaming is one of the industries most impacted by the seismic force of blockchain and decentralization, and NEAR protocol is positioned as one of the leading platforms for developers to build the future of gaming. For those that don’t know, game-fi refers to any game that is built on the blockchain. Whilst this may sound underwhelming, being built on the blockchain allows for a host of radical new functionalities and forms in gaming previously unimaginable. So, imagine an open-world online role-playing game in which the coins and assets you earn translate into real-world assets. Imagine then transferring these assets between games and trading them in external marketplaces as part of rich economies that expand far beyond single games. These are just some of the possibiliti...

What is NEAR Protocol?

NEAR protocol is a layer 1 blockchain with big ambitions. With its declared mission to put usability first and change the world of web3, NEAR is set to open out the web3 space to millions of new developers, programmers, and users. As a smart contract enabled, layer 1 blockchain, NEAR Protocol has inevitably been positioned as a competitor to the Ethereum network, and is placed alongside a handful of other layer 1 networks such as Polkadot and Solana as ways to provide more scalable alternatives to Ethereum. Within this, NEAR distinguishes itself with its ambitious speeds, which are set to reach 100,000 tps once it is fully implemented, making it capable of speeds well and beyond the current 7000 tps of Visa. Throw in transactions that reach finality in 1–2 seconds and that cost less than a penny, and it’s no wonder why many developers are flocking to NEAR. This article will serve as an introduction to NEAR Protocol, unpack some of the innovations of its underlying technology, and underscore the importance of securing the NEAR ecosystem with a NEAR smart-contract audit. How it does it NEAR achieves these numbers through its innovative use of sharding. Sharding is the process by which the network is split into fragments –‘shards’ — so as to lessen the computational throughput on each node. This system means that each node only has to handle the portion of the network’s code that is designated to it, rather t...

How Avalanche is Innovating in Three Key Sectors

rt The radical potential of Avalanche’s technology is already supercharging innovation in some of the most disruptive sectors in the web3 space. It’s one thing to sing the praises of Avalanche’s underlying architecture, it’s another to understand how that architecture is facilitating growth in real terms. This article will do just that, taking you through some of the most exciting developments in the web3 space today, and explaining how Avalanche is designed to meet their specific needs and capacities. It will then detail how the Avalanche network, in conjunction with an Avalanche smart-contract audit, works to foster unparalleled security throughout its ecosystem. Game-Fi One of the most eye-catching developments in the web3 ecosystem in recent years has been the growth of game-fi, also known as P2E (play-to-earn), which marks a revolution in the gaming world by allowing players to immerse themselves in online worlds like never before. What’s more, game-fi allows players to earn things such as cryptocurrencies and NFTs by completing tasks, battling other players, and trading in the in-game economy. This rich world of trade and interaction even extends beyond the limits of one game, as the blockchain allows in-game assets and characters to be transferred across to other applications in the ecosystem. So an exclusive skin or hard-won item can be traded and exchanged in NFT marketplaces and crypto exchanges. Given th...

How Avalanche Tackles the Scalability Problem

To understand exactly how Avalanche is a game-changer within the web3 ecosystem, we first have to understand how it works to both disrupt and resolve some of the longstanding problems that have faced the blockchain industry. Perhaps the most important among these is the scalability problem, which for a long time has been one of the biggest barriers to mass adoption. This blog post will take you through the history of the scalability problem, look at some of the various attempts to solve it, and spotlight how Avalanche has resolved it through its innovative use of subnets. It will then go on to outline the importance of fostering security amongst the subnet ecosystem through Avalanche smart-contract audits and other security tools. The Scalability Problem The problem of scaling blockchains is in many ways a problem of success. In the early days of bitcoin, the number of users and transactions that the network had to handle was relatively small, and as such, it wasn’t difficult to keep the network both cheap and fast. However, as bitcoin became increasingly popular, the growth of its user base began to outstrip the growth of its network, which caused the speed of transactions to decline, and the costs to increase. To understand why this is, we have to look at the architecture of a blockchain. Each ‘block’ in a blockchain has the capacity to contains a limited number of transactions. So, bitcoin has a blocksize of 1MB, wh...

Understanding Avalanche’s Consensus Mechanism

For anyone looking to get a sense of the scale of innovation that Avalanche enables, understanding its novel solution to achieving consensus is a good place to start. In a space that is crowded with projects claiming to offer a radical new technology, it can be hard to discern whether a project is really offering innovation, or is just looking to build some hype. To help you separate the wheat from the chaff, this blog post will take you through one of the biggest innovations that Avalanche’s technology offers, its consensus mechanism, contextualizing it within the history of the solutions to achieving consensus to show how it solves many of the limitations of the prior art. Moving beyond this, this blog will then show how Avalanche smart contract audits are essential for any project seeking to build on the security offered by Avalanche’s novel approach to consensus, and will argue that any Avalanche smart contract audit worth its salt will need a detailed understanding of how its network handles consensus. What is a Consensus Mechanism? First, let’s take a look at how consensus has been formed historically to get a better understanding of how Avalanche disrupts the space. A consensus protocol– how a system or collection of machines agrees on something– is one of the most important functions of a distributed computing system. The problem that consensus protocols are designed to resolve was identified by the compu...

What is the Avalanche Network?

Avalanche is one of the most exciting networks to enter the Web3 space in recent years. Developed by a team led by Emin Gün Sirer, former Associate Professor of Computer Science at Cornell University and leading thinker in distributed systems, Avalanche offers developers and investors a winning combination of low fees, lightning speeds, reliability, and the kind of scalability that drives mass adoption. Undergirded by a sustainable, eco-friendly ethos as well, it is no wonder that Avalanche has become one of the major players dominating the Web3 ecosystem. Within the current Web3 landscape, developers and thought leaders continue to wrestle with the best way to realize interoperability, whether the future will be multi-chain or cross-chain, and of course, how eventual regulation will shape the space. One capability that makes Avalanche innovative is Subnets, a game-changing technology that empowers developers to create projects on networks that they can design to fit their needs. Subnets are deeply customizable and inherit speed and security from Avalanche’s Primary Network. Subnets are set to reshape the way we think about blockchain optimization. Rather than have to fit within the pre-defined parameters set by a foundational blockchain, developers and users can define their own communities, validators, and governance mechanisms. This is a gamechanger in terms of achieving mass adoption, as it provides a pathway for proj...

Securing Blockchain Beyond Web3

Given the meteoric rise of the technologies that make up the web3 ecosystem, it can be easy to forget that blockchain technology has numerous use-cases and applications outside of cryptocurrencies, NFTs, and the Metaverse. The truth is that blockchain technology is being used to make a diverse range of industries more scalable, efficient, and secure by introducing practices of decentralization. It may not seem like it, but blockchain’s role in these sectors is arguably as disruptive as its more headline-grabbing presence in web3. And, just as web3 security technologies and practices are required to protect web3 infrastructure, sectors that use blockchain technology to modernize their industries are having to develop novel security practices themselves. Unsurprisingly, this mission to secure blockchain use beyond web3 can learn a lot from the hard-won lessons of web3 security. Health care One area in which blockchains are revolutionizing vital infrastructures is healthcare, which has been making use of blockchains to share and store medical data, improve patient care, and streamline medical supply chains around the world. Recording and accessing a patient’s medical records is a vital part of any modern healthcare system. Yet the existing storage infrastructure in place is notoriously slow and inconvenient, with different institutions using different systems, and the transfer of information between these systems being convo...

What are Public and Private Keys?

Public and private keys are one of the pivotal technologies that make cryptocurrencies possible by allowing users to transact without the need for a third party to verify the transaction. This in turn is necessary to facilitate the decentralized, trustless architecture that has made blockchain and web3 such a revolutionary technology. Anyone hoping to have an understanding of web3 security will need to have an understanding of public and private keys, both in terms of how they work together, and also of the various web3 security risks that they entail. — Cryptography - Some form of private keys have been present from the beginning of cryptography, which was led by academic and military personnel seeking ways to encode messages which were then decoded using a secret phrase. This phrase could be used to first encrypt, then decrypt the message. Whilst useful, there was a major weakness in this design in that the same phrase was used to both encrypt and decrypt the message, meaning that if the phrase were to be compromised, an unauthorized person could both access the information, and also impersonate the person sending the message. This earlier process of encryption is called ‘symmetric encryption’ as both sides of the process used the same phrase. In the 1970s cryptographers developed ‘asymmetric cryptography, which resolved the problems of the prior art by splitting the process in two to create a ‘public’ and ...

What Can We Learn from the Luna/Terra Crash?

On May 7th 2022, in one of the biggest upsets in crypto history, the Luna/Terra ecosystem came crashing down, after its native token slumped and its popular stablecoin TetherUSD (UST) de-pegged, setting off a death spiral that sent shockwaves throughout the web3 ecosystem. The Luna/Terra crash has become a landmark moment in the recent Bear market, with widespread implications for web3 security and the future of the industry. This article will take you through what happened in the Luna/Terra crash, the lessons to be learned from it, and what users and web3 projects can do to help better protect themselves from the fallout of such upheavals going forward. — Stablecoins - To begin with, we have to understand the architecture behind the UST stablecoin and how it could be exploited in an attack. As you likely know, a stablecoin is a form of cryptocurrency that has its value pegged to another currency, typically the US Dollar. Stablecoins serve a vital role in facilitating crypto trading, serving as a key point at which cryptocurrencies intersect with traditional finance– an intersection that is of serious concern to many regulators. The most ‘stable’ of these stablecoins are fully backed by assets of their issuers. For example, the USDC coin issued by Centre (a joint venture between Coinbase and Circle) is backed 1:1 by dollar reserves, and regularly publishes audited reports on its backing. Similarly, Tether claims...


CertiK Closes $60 Million Funding Round from SoftBank Following $88M Ser...

    CertiK – a Web 3 and blockchain security firm – has secured an additional $60 million investment from SoftBank Vision Fund 2 and Tiger Global. This follows the firm’s $2 billion valuation last month, after an $88 million round in which Tiger Global also took part. With the new funding, investments in CertiK over the past nine months have surpassed $290 million. It also marks SoftBank’s first investment into the web 3 security space. The Japanese investment manager has previously put money towards crypto infrastructure provider BlockDaemon, and popular crypto exchange FTX. In a press release from CertiK, Softbank Managing Partner Dennis Chang claimed that security concerns are currently holding the Web 3 industry back from its full potential. “We believe CertiK combines deep expertise in cybersecurity, blockchains, and systems verification to provide companies with a leading solution in blockchain security and auditing,” he said. Indeed, while the decentralized web has attracted interest from major entrepreneurs, smart contract exploits and scams still plague the space. For example, Axie Infinity’s treasury was struck by a $600M Defi hack earlier this month due to a hacker compromising the wallet’s private keys. In early January, $3 Million were lost from an Algorand-based DEX after bugs in its smart contract were exploited. CertiK provides security products like code-auditing and Skynet, to locate smart contract bugs and provid... read More

    Certik, a Web3 and blockchain auditing and security firm, has raised $88 million in its recent B3 funding round. The round, which was led by Tiger Global and included Goldman Sachs as an investor in the firm, gives the company a valuation of $2 billion. This doubles the valuation that Certik reached via its last funding round in November 2021. Certik Reaches $2 Billion Valuation Certik, a blockchain auditing firm, has closed its Series B3 financing round with a significant increase in investments. The company raised $88 million, with Tiger Global, Insight Partners, and Advent International leading the round, and with the participation of Goldman Sachs and other current investors. With this funding round, the company has managed to reach a valuation of $2 billion, doubling the numbers it obtained in its Series B2 funding round in November 2021, which gave it a valuation of $1 billion. Regarding how the company has managed these funding rounds and their successes, Ronghui Gu, founder and CEO of Certik, told Techcrunch: We have raised four rounds in the past nine months and the valuation has grown more than 10 times. We haven't touched any money in the past four rounds. The money is in the bank and the reason is because CertiK is a profitable business. The firm attributes this growth to the importance that blockchain security and pre-deployment audits have taken on now that there have been massive hacks and exploits involving bridges, li... read More
